To all whom t may voiler/rn.'

lie it known that l, EDWARD S. pararon, citizen of the l'nited States, residing at Chleago, in the county ot' ('ook and State of illinois, ful Improvements in Dashboard Lamp- Hoelcets: and l do hereby declare the following to he a full, clear, and exact description of the invention, Sue-h as will enable others skilled in the art to which it .uppertains to make and use the same.

My invention relates to sockets for electric lamps, and in one of its .aspects relates to means for maintaining `a.co\vl`holding easing in operati veposition, and to means for simultanwusly securing a cowl-holding socket portion and the main (or electrically functioning and lam -holding) socket portion to a support. n another aspect, my inveotiiirl aims to provide simple, handsome and cheaply constructed means for mounting a soelcet at an angle to a dashboard or other support and for Vpreventing the appiiauee from rotating with respectto sach a support. ln still another aspect, luy-n1- \.ention aims to equip the shell of a socket with simple formations arranged for elaiuping a eowl-holding outer easing between itself' and a supporting member. Still other oblieetsv will appear from the following sperifif'ation and from the accompanying drawings in which* Figure l is a vertical and central section through a la mp socket embodying my invention and secured to a metal dashbealrd.

Fig. 2 is a bottom view of' the threaded insert in the interior of the base member of my appliance.

Fig. Il is a fragmentary transverse sei-tion through a dashboard antl another einbodinient ol' in v invention mounted th'ereon.

Fig. -t is a fragmentary transverse view ol' a basi portion ol'lanother embodiment ol' my invention.

ln its pi'el'erned l'orln. my invention relates to mountngs for lanip-soelv'et bodies, being partimdarlv adapted for use with the types ol' soelcets in whieh 'a .shell l t is equipped at one end for interlocking with the base of a lainpZ. and in whieh the eiri-uit is made tothe larnp,at least in part. by a eondnetor carried by an insulating body Il mounted within t'lie shell l. when soelt'els olI this rlass are used in -onneetion with lamp"y intended l'or illuminating speed indieators and tb?l lihe on the dashboard of an automobile. it is desirable that all exeept` the have invented certain new and nse.

-ai'eollar Il having a downwardly distributed rays of the lamp should be concealed, so as to avoid glare the eyes of the observers. lt is also desirable to mount the socket in an inclined position, so that the light may effec` tively be thrown both downward and toward the dashboard and the instruments mounted on the latter. However,an oblique extension of the sotket shell through the dashboard would involve both difficulties of properly fastening the shell to the dashboard, and a` rather unsightly construction, and might also involve ditileulties in preventing the obliqnely placed shell from being rotated about the portion of the dashboard to whieh it is fastened, thereby departing 'from the desirable downwardly inclined position. To avoid these diflieulties and to secure both a handsome. rigid and relatively simple eonstrnetion, l desirably provide the shell l of the lamp socket with a laterally projet-ting formation, sin-ll as a bead 4. which bead engages an inwardly direeted flange on an outer easing 5 having its forward end VAequipped for supporting a enwl ti. 'l`hen l butt the rear end ot' the easing 5 against a supporting member seeured to the dashboard T and so arranged that the surl'aee against whit-li the rear end ol' the easing 5 abuts, is disposed oblirplely to the fave of the dashboard i'.

'nf'h a supporting member desirably eonsists oi' a bushing having a flange tw integral with a threaded tubular shank Sl. whieh Ishank extends through a perforation in the dashboard and has a nut lll threaded on il. IHeeured to the llanged end ol' the bushing is base engaging the llange H and having an inwardly turned end l2 formed to receive the inner elnl ol' shell l. llnd l2 is obliipu| to the dashboard 7 and is engaged by the inner end ol' easingr. 'l`he shell l is threaded and engaged b v a nut l5 whieli latter abuis the end l2 oi the eollar ]l. 'l`he eollar ll has its opposite end spun over -the peripheral portion ot the [lange H. From the loregoing it will be apparent. that. upon tightening nut It). the flange H and therewith theHollar ll wfl be drawn. toward the dashboard 7. causing the Ispun end ol' the roll-ar ll, lo be inipinged against the dashboard 7. lSilnilarly upon tightening nut l5. shell l will be drawn toward the dashboard i' and dueto bead l engaging the torus-ivd end ol' the easing 5 the latter will have its inner end tightlv ivnninged against end l2.

the flange ol' thesbcll 1T.

The parts are thus rigidly held in position with the casing .'3 inclined and at the same time an ornamental and attractive structure is provided. To prevent the structure from rotating a slot is preferably formed in the dashboard 7, and a lug 23 is preferably struck-out from the flange 8 so as to project into the slot as depicted in Fig. 1.

Lugs 22 may be used for holding nut l5 in place, these lugs preferably being struclv out from the end 12 as shown in Fig'. l.

In Fig. 3, a modified form of the invention is shown, wherein easing 1G of the socket is rigidly fastened to a threaded shell 1T fitting directly thereover and provided at its forward endA )vith an outwardly directed flange. Thread upon this shell 1T, is a nut 18 engagl" with the rear fare of the dashboard. and a forward nut 19 arranged eowl-holdimr collar lll for clamping ,both a and a easing sleeve 2l between nut 19 and Ilere also the threading ol the socket shell into a nut assoelated, with the support automatimdly clamps both the cowl-supporting shell and an ornamental easing part between the flange on tbe socket shell and the dashboard, thus uniting these varionselernents into a rigid strnctuxie, the forward nut 19 serving onl to hold the adjacent parts together until the socket is attached to the, dashboard.

In Fig. 4, a further modified form of the invention is illustrated and wherein the collar 11 has its outer or front end formed with an elongated part which is threaded onto shell 1 so as to take the place of nut 15 in Fig. l, and instead of the spun feature of the latter figure the collar 1l is formed with integral lugs 13 and 14 which are projected through o )enings provided therefor in flange 8 and headed into engagement with the flange.

l claim as my invention:

A niountin for a lamp comprising a lamp socket shel threaded at its rear end and having a lateral enlargement on a more forward portion thereof, a supporting member including a eollar recessed for engaging the rear ond of the socket shell, an outer casing interposed between the collar and the lateral enlargement on tbe socket Shell, and a. nut threaded on the. rear end of the socket shell to clamp the outer easing in its said inA terposed posit ion.

'2.
